Abstract (en)
Hydraulic press for the compression-moulding of plastic materials; the press comprises a lower fixed platen (10) and upper movable platen (12) sliding along guide columns (11) extending from and movable respect to the lower platen (10); sensing means (25, 26) are provided to control the downwards movement and velocities of the upper platen (12) and guide columns (11), sending control signals to a logic control unit (27) programmed to start the descending movement of the columns (11) during the downward movement of the upper platen (12) and to activate clamp means (16) to lock the upper platen (12) to the moving columns (11) when the relative speed between said upper platen (12) and columns (11) is zero. <IMAGE>
